Talk:Charales

Citation needed

"Cytoplasmic streaming is caused by the microfilaments found inside the cell, as proven by the use of cytochalasin B to stop streaming."

Requires, in my opinion, a citation.

Maybe one of these

Questions

Does the encrusting of of the algae by CaCO3 have any (potential) economic value? Are any other minerals (eg Mg,Sr,Zn,Mn,Fe++) ever sequestered along with the Ca? Does the lime provide protection? Does "acid rain" dissolve the lime? Are there organo-Ca chemicals or polymers created? The picture shows a verdant place; do these algae also grow in high osmotic or electrolyte areas such as alkali ponds? What controls the elaborated structure of the lime aggregates, and what variants are known, in vivo and in vitro? Are they edible? Just curious.... regford 18:19, 3 April 2006 (UTC)

The family Characeae (order Charales) has 6 modern genera but not 4!!! Dmitry Kapustin 19:27, 1 January 2007 (UTC)

I have found (in the books):- Chara, Lamprothamnium, Nitella, Nitellosis, Tolypella. There may be another genus somewhere! I'll have to have another look. Any ideas?Osborne 16:06, 31 January 2007 (UTC)

And the sixth one is Lychnothamnus. Look: Krause W. Charales(Charophyceae) //Süβwasserflora von Mitteleuropa. Band 18, 1997. Dmitry Kapustin 15:07, 18 February 2007 (UTC)

Split needed

The article is confused/confusing, because it assumes that the Charales and Characeae have the same circumscription. In many treatments, it is the case that the Characeae are the only family in the Charales that has living (extant) species, although as of February 2022, AlgaeBase puts Nitellopsis in the family Feistiellaceae. All sources I've looked at that include fossils agree that Charales includes multiple fossil families. So there should be two articles: a brief one on the order Charales, and a longer one on the family Characeae, I think in the broad sense in which it includes Nitellopsis.
